Curry is one of the most flexible comfort foods on the planet, but its vitamin C content varies wildly depending on what goes into the pot. A tomato-heavy vegetable curry can deliver a meaningful dose, while a meaty curry made only with onions and spices may give you very little. This calculator estimates the vitamin C in a portion of curry based on curry style, portion size, and the fresh ingredients you add at the end.
Whether you are planning a post-workout meal, tracking micronutrients, or helping a family member meet their daily vitamin C needs, this tool turns a rough guess into a useful estimate. Enter how much you are eating, choose the closest curry style, tick any fresh add-ons, and the calculator returns milligrams of vitamin C plus a percentage of the 90 mg Daily Value.
🍛 Curry Vitamin C Calculator
Estimate how much vitamin C is in your curry based on portion size, style, and fresh high-C add-ons.
How to Use This Calculator
Start by entering how much curry you plan to eat. You can type grams directly, or use the dropdown to enter cups or servings. A standard cup of cooked curry weighs about 245 g, and a typical restaurant serving is close to 300 g. Next, pick the curry style that comes closest to your dish, because the calculator uses a different vitamin C density for each style. Finally, tick any fresh add-ons such as lime juice, green chili, or coriander that you add just before serving; these contribute vitamin C beyond the cooked base.
How the Estimate Works
The calculator starts with a vitamin C density in milligrams per 100 g for each curry style. These densities are based on typical ingredient proportions and on USDA FoodData Central values for tomatoes, onions, peppers, spinach, potatoes, citrus juice, and chili peppers. The tool multiplies the density by your portion weight in grams, then adds the vitamin C from the fresh boosters you selected. The final amount is compared with the 90 mg Daily Value used on nutrition labels in many countries.
Example: A 300 g serving of vegetable curry at 7 mg per 100 g gives a base of 21 mg. Adding a lime wedge (4 mg), a small green chili (6 mg), and a coriander sprinkle (3.5 mg) brings the total to about 34.5 mg, or 38% of the Daily Value.
Reference: Vitamin C Densities by Curry Style
The values in the table are typical estimates for a cooked curry and can vary with recipe and cooking time.
| Curry style | mg per 100 g | Main vitamin C source |
|---|---|---|
| Mild chicken curry | 3.5 | Tomato base, onion |
| Vegetable curry (peppers, spinach) | 7 | Bell pepper, spinach |
| Lentil dal / chickpea curry | 2.5 | Tomato, lemon finish |
| Thai green curry | 6 | Green chili, lime, herbs |
| Japanese curry | 4.5 | Potato, carrot, onion |
| Beef or lamb curry | 2 | Low produce content |
| Fish curry with lemon/lime | 7.5 | Citrus juice, chili |
| Paneer / tofu curry | 5.5 | Tomato, peppers, spinach |
Fresh Add-Ons Make a Real Difference
Cooking lowers vitamin C, so any fresh ingredient added near the end of cooking is especially valuable. A spoonful of lime juice, sliced green chili, or chopped coriander can add several milligrams and also improves flavor. If you eat curry often, adding a handful of spinach or extra tomato to the sauce is an easy way to raise the base level without changing the dish much.
Tip: Squeeze citrus over the curry right before eating rather than during simmering to preserve more vitamin C.
Frequently Asked Questions
Is curry a good source of vitamin C? It can be. Vegetable curries made with peppers, tomato, and spinach provide meaningful amounts, while spice-only meat curries give very little. The curry style selected in the calculator determines most of the result.
Does cooking destroy vitamin C? Yes, vitamin C is heat-sensitive and some is lost during simmering. The calculator's densities reflect typical cooked curries, so adding fresh ingredients at the end is the best way to offset that loss.
Why is the Daily Value set at 90 mg? The U.S. Food and Drug Administration uses 90 mg as the Daily Value for vitamin C for adults. Many adults need about 75–90 mg per day depending on age and sex. For detailed guidance, see the NIH Office of Dietary Supplements fact sheet.

Limitations
These values are estimates, not lab results. Actual vitamin C depends on ingredient freshness, cooking time, and the exact recipe. Use this calculator for meal planning and general nutrition awareness, not as a substitute for medical advice.
